cmeel-boost

# Assume a C++ project 'my_cpp_lib' that uses Boost. # # 1. pyproject.toml for a Python package that depends on my_cpp_lib # and needs cmeel-boost as a build dependency: # # [build-system] # requires = ["cmeel[build]", "cmeel-boost~=1.89.0"] # build-backend = "cmeel.build" # # [project] # name = "my-python-package" # version = "0.1.0" # # 2. CMakeLists.txt for my_cpp_lib (e.g., in a 'src' subdirectory): # # cmake_minimum_required(VERSION 3.15) # project(my_cpp_lib LANGUAGES CXX) # # # Find Boost components. cmeel-boost will have installed Boost # # in a location discoverable by CMake through CMAKE_PREFIX_PATH set by cmeel. # find_package(Boost 1.89.0 REQUIRED COMPONENTS system thread) # # add_library(my_cpp_lib SHARED my_cpp_lib.cpp) # target_include_directories(my_cpp_lib PUBLIC ${Boost_INCLUDE_DIRS}) # target_link_libraries(my_cpp_lib PUBLIC Boost::system Boost::thread) # # 3. my_cpp_lib.cpp (example C++ file using Boost): # # #include <iostream> # #include <boost/version.hpp> # #include <boost/system/error_code.hpp> # # extern "C" void say_boost_version() { # std::cout << "Boost Version: " << BOOST_VERSION / 100000 << "."; # std::cout << (BOOST_VERSION / 100 % 1000) << "."; # std::cout << (BOOST_VERSION % 100) << std::endl; # boost::system::error_code ec; # // Example use, not doing anything meaningful with ec here # if (ec) { # std::cerr << "Error: " << ec.message() << std::endl; # } # } # # 4. To build a wheel for 'my-python-package': # (Ensure your environment has a C++ compiler compatible with Boost.) # python -m pip wheel . # Note: This code block demonstrates the C++/CMake usage. The `python -m cmeel cmake` command # is typically run internally by `pip` when building a `cmeel`-based package that depends on `cmeel-boost`. # For debugging or manual usage in a C++ project outside `cmeel`, you might run: # export CMAKE_PREFIX_PATH=$(python -m cmeel cmake) # cmake -S . -B build # cmake --build build import os # Placeholder for a Python script that might invoke the C++ library (if bindings existed) # cmeel-boost itself does not provide Python callable functions. print("cmeel-boost provides C++ libraries, not direct Python imports for Boost functionality.") print("To use it, your Python package must be built with cmeel and link against Boost in its CMake project.")
